Execute the selected no-op rather than freeze its spelling, while rejecting /bin/true to model the NixOS failure. Mark the regression Linux-only and retain the current user-bus environment handling. Consolidates the earlier NixOS scope-probe report and fix in #102587 with the PATH-independent payload from #105436. The fallback resolver is not needed when /bin/sh is used directly.
